Crash due to _fini - wine-devel

31 May 2004


      Hi
i am trying to link  wine library(msvcrt.dll.so)  with my code but i getting
segv in  _fini call of msvcrt library
Please tell me a way so that i can use wine libraries directly without
winegcc or specs file
on using winegcc  for code which contains new and delete operator it gives 
 undefined reference to following symbols
operator new(unsigned)
operator delete[](void*)
_Unwind_Resume
__gxx_personality_v0
please help me to resolve above symbols
waiting for response
Thanks
Rajeev
Test Program :
#include <dlfcn.h>
#include <direct.h>
#include <math.h>
#include <stdio.h>
main()
{
char *a;
char *b;
double d;
void *mod, *ker;
const char *error;
mod=dlopen("msvcrt.dll.so",RTLD_LAZY);
ker=dlopen("kernel32.dll.so",RTLD_LAZY);
if(mod)
{
if ((error = dlerror())) {
    	printf("Couldn't find getcwd: %s\n", error);
    }
if(dlsym(mod, "getcwd")){
    	printf("found");
    	b=getcwd(a,20);
    }
dlclose(mod);
    dlclose(ker);
} //end if	
return (0);
} //end main
